Letters Patent No. 99,142

, dated January. 25, 1870.

IMPROVLEMENT IN RAILROAD-TIE LIFTERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern the whole showing how it may be applied.

Figure 2 is a perspective view, showing the trackraiser and its application to one of theties of the road.

Corresponding letters denote corresponding parts iu both figures.

This invention relates to -that class of devices which are used for raisingr those portions of a railroad-track which have been depressed below a proper le 'el, and

thus restoring the proper alignment of the upper surface of such roads. i

Devices have heretofore been constructed similar in Asome respects to this, but which have been placed upon cars for use, which fact has made them costly and cumbersome, it being necessary to remove the car from the track upon the passage of each train.

The usual method of raising the ties of railroads has, however, been by means otl a lever placed under the outer-'ends ofthe ties, which method has been found to `be very obj ectionable, because of the fact that when Vit is used in deep cuttings, there is not room to 'operate levers so placed or applied.

This invention is designed to supply a cheap and reliable device for the purpose above referred to, which shall be free from the objections above recited; and to V this end,

- It consists in a frame-work arranged to rest upon,

the ties of a railroad, and to be used in combination with a lever and cross-bar, which bar is to be provided with books at v`or near its ends to grapple'the tie's, so thatwhen the outer end of the lever is borne down, the tie shall be raised.

A, in thc'drawings, refers to a frame-work, which maybe of wood or metal,'it consisting of a transverse portion, A, which is to be rigidly attached to the horizontal portion A1, the lower surfaces of which are to be of sufcient area to insure its permancncy when in positionto be used.

A2 refers to a post or standard, which is to be secured to the upper surface of the base A and A1, it being supported in its vertical position by means ofa series of braces, as`shown in fig. 2.

The upper end of this standard or post is to be bifurcated to receive the lever B, the fulcrum of which is in 'said post.

B refers to the lever, which is used for raising the lties. It is to be 'pivoted to the standard A2, as above stated, the long arm extending rearward for any dcsired distance, while the short. arm extends forward for a distance sufficient to give the required movement to its outer end, to which there is attached a chain, l), which extends from its point of connection with .such lever in two directions, and is united at each of its ends'with the cross-bar O, \vhich isvto be of sufficient size to give the required strength, and-of a length about equal to the width of' the track.

Near the outer ends of the cross-bar C there are secured upon cach side thereof two dogs, E, they being arranged in pairs, and so that when placed in position for raising a tie, they will penetrate such tie, as shown in fig. 1, and thus, as the outerend of lever B is borne down, these hooks are made to more firmly grip the tie, and thus it will be raised, and may be held up while the earth is tamped beneath it.

F F refer to the ties of the track, which may be of the usual form and arrangement, but which, as they form no part of my present invention, need not be more particularly described.

Having thus described my invention,

What l claim, and desire to secure by Letters latent, is

The within-described track or tie-raiser, consisting of a base for supporting the sa/me upon the ties or upon the ground, a vertical post or standard for supporting the lifting-lever, a cross-bar, and a series of hooks i'or communicating the motion of the lever to the tie, the parts being all constructed and arranged substantially as and for the purpose set forth.

In testimony whereof, I have signed my name to this speciiication, in the presence oi' two subscribing witnesses.

ELIJAH BOMAR.
